Detailsinfo

A vulnerability classified as critical has been found in dbt-labs dbt-mcp up to 1.17.0. Affected is the function _run_dbt_command of the file src/dbt_mcp/dbt_cli/tools.py of the component Model Context Protocol. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

dbt-mcp is a Model Context Protocol server for interacting with dbt. Prior to 1.17.1, _run_dbt_command() in src/dbt_mcp/dbt_cli/tools.py appended unsanitized node_selection and resource_type values to the dbt subprocess argument list, allowing an MCP client to inject dbt global flags such as --profiles-dir, --project-dir, and --target into subprocess.Popen even though shell=False prevents shell metacharacter injection. This issue is fixed in version 1.17.1.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-44968 since 05/08/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
